tis_setspecific - Changes the value associated with the specified thread-specific data key.
Standard C Library (libc.so, libc.a)
const void *value);
Thread-specific data Key that identifies the data to receive value. Must be obtained from a call to tis_key_create(3). New value to associate with the specified key. Once set, this value can be retrieved using the same key in a call to tis_getspecific(3).
This routine sets the value associated with the specified thread-specific data key. If a value is defined for the key (that is, the current value is not NULL), the new value is substituted for it. The key is obtained by a previous call to tis_key_create(3).
Do not call this routine from a data destructor function.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The key value is invalid. Insufficient memory exists to associate the value with the key.
Functions: tis_getspecific(3), tis_key_create(3), tis_key_delete(3)
